I think Quickbooks need to look into revaluing zero valued foreign balances.  These exchange differences are feeding through to the AR balance in TB and BS and are completely incorrect.  We have a very high volume of foreign customers and vendors and I need some way to deal with this.  Double checking the exchange rate on the invoice and matching it to the payment is time-consuming.  Maybe we go back to a fixed exchange rate for the whole year, but that seems to be really bad practice.
